VACUUM PL JM Pl-NG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 232,638, dated September 28, 1880. Application filed May 14, 1880. (No model.) Patented in England January 23, 1880.

To all whom it may concern:

Be it known that we, GERHARD FRiNes and RICHARD MULLER, subjects of the King of Prussia, residing at the city of Berlin, in the German Empire, have invented certain new and useful Improvements in Vacuum Pumpl ing Apparatus; and we do hereby declare the apparatus for raising water from wells and for accelerating and increasing the flow of water to the well from the surrounding earth strata; and the said invention consists in an apparatus of novel construction operating to form a practically permanent vacuum within the well, and to receive and discharge the waters therefrom.

In the accompanying drawings, Figure l is a vertical transverse section taken on the broken line 00 a: of Fig. 3 of the apparatus. Fig. 2 is an elevation, partly in section. Fig. 3 is a plan view thereof. Fig. 4: is a horizontal transverse section taken on line z y of Fig.

2; and Fig. 5 is a vertical transverse section of.

part of the vacuum vessel or receiver, taken on line 2 z of Fig. 3.

In carrying out our invention the orifice of the well A is made air-tight by any convenient or preferred means, preferably by means of the supporting base or frame of the receiving and discharging apparatus, and in prac tice we line the walls of the well, either wholly or so much thereof as may be necessary to prevent the caving in of the earth, with a jacket of metal or other suitable material.

A pipe, as, connects the well with the vac- .uum vessel or receiver, which is thus made to practically form a continuation of said well,

and said pipe at is provided with a throttle or other suitable valve, a, whereby the flow of the water to the apparatus may be regulated. Thisvalve is shown in dotted lines, Fig. 1.

B represents the vacuum chamber or vessel or receiver, composed preferably of a cylindrical body, I), a dome or semi-cylindrical head, b, and a bottom, 12 having the induction-pipe B, that is connected with the pipe at extending by springs c with an arm, 0 The object of these springs, the tension of which is outwardthat is, the tendency thereof is to draw the valves open-is to counterbalance the effect of the vacuum within the cylinder B, leaving the operation of the valves to the press nre of the. water only. Each pipe G O is provided with a discharge-valve, c, in all respects like the induction-valves c, and the pipes are grouped or maybe grouped in couples around the cylinder B, one or more of such couples being employed according to the capacity of the well. Each couple of stand-pipes O G is connected at its upper end by a canal, c and each pipe of the couple has a port, 0 open to the atmosphere under certain conditions; and upon the top of each couple is bolted a valve chest, D, within which operates a slide-valve, D, that is made to alternately and periodically open and close the port 0 of the pipes G (3.

To prevent sand or other impurities from entering the ports 0 we employ a guard or shield, K, Fig. 2, formed of two curved metallic plates bolted to and moving with the slidevalve D. The valve-stem at of the valve D carries at its outer end an eccentric strap or box, d, and is supported and reciprocates in suitable bearings on the bracket-arm D Figs. 2 and 3. Within the strap (1 operates the eccentric c of the disk 6, that is mounted upon one end of a shaft, E, which revolves in bearings formed in the bracket-arm E, as shown,

Figs. 2, 3, and 5. The shaft E also carries a bevel-wheel, 6 that meshes with a like pinion, f, upon one end of a shaft, F, that passes through a suitable stuffing-box, F, into the cylinder B, where it is properly supported'by a hollow bracket, B provided with a suitable bearing-sleeve, as shown, to prevent access of air from without into the cylinder B.

Upon its inner end the shaft F carries a bevel-wheel, f, that meshes with a similar pinion, g, mounted upon the lower end of the spindle G of the turbine or water wheel G,

the upper end of said spindle revolving in and is supported by suitable bearings formed in the spider or cross-tie g.

A suction-pipe, H, is connected with each 5 pair of pipes O O at or near their upper ends, or with the casting or housing that connects said pipes together, said pipe being also connected with any suitable air-exhaustin g apparatus, such as an air-pump. These being well known, we have deemed it unnecessary to show.

such in the drawings.

The cylinder B is connected with the suctionpipe H by a pipe, L, that is provided with a stop-cock, Z, whereby any air that may be car- I 5 ried into the cylinder by the water is from time to time exhausted to maintain the permanent vacuum in the well and its extension,

the cylinder B.

The operation of the apparatus is as follows: By means ofany suitable exhausting apparatus avacuum is formed within the well and receiver B, as well as one of the stand-pipes of the couple-say, for example, pipe (1, its port 0 being closed by valve D,while the port 0 of pipe 0 2 5 is open to the atmosphere. The water from the well will now riseinto pipe at, when the stop-cock Zmay be closed, the vacuum within the well and the cylinder being now practically a permanent one. From the pipe (I. the water rises into' pipe B, and from thence through the chutes of the turbine into the cylinder B, and thence through valve 0 into pipe 0, where the water will rise as in the cylinder until the turbine G is submerged, when it will rotate, 3 5 thereby rotating the shaft F through the spindle G and the gear-wheels gf, and this rotation will be communicated by the shaft F, through its pinion f, to the counter-shaft E, through its pinion c and the rotation of the 0 latter shaft will, through the eccentric e a, re-

ciprocate the valve-stem and valve D to open the port 0 of pipe 0 and close that port of pipe 0. Atmospheric air having now access to the pipe 0, its pressure upon the surface of the water will at once open the dischargevalve 0 and close the induction-valve c, the contents of pipe 0 being thus discharged into a suitable reservoir, It. At the same time the discharge-valve of the pipe 0 is closed and a vacuum formed therein, the water from cylinder B rushing through the induction-valve into said pipe 0, and will rise therein, as be fore described, until the turbine is again rotated to open the port 0 of pipe 0 and dis- 5 5 charge its contents, as above set forth.

When the flow of water from the well is suf- -ficiently great to rotate the turbine continuously, the heart-shaped or other eccentric is so constructed as to operate the valves at stated periods, which are regulated by the capacity of the pipes O O.

It will be apparent that any other motor adapted to be operated by the flow of the water into the receiver B may be employed.

We have, however, found in practice that the turbine gives the best results.

It is also apparent that the apparatus may be readily converted into a fountain of many jets grouped around a central cylinder, B, the water being thus discharged into suitable ornamental moldings, figure-heads, or other like devices, having applied thereto a series of jets instead of being discharged in a large volume into a reservoir, as shown.

From time to time, or whenever required, the air that may be carried into the cylinder B by or with the Water is exhausted therefrom by the exhaust apparatus through pipe L, and, instead of using the latter pipe when forming the primary vacuum, a separate pipe may be connected with the cylinder B at a, Fig. 1.

Having now described our invention, what we claim is 1. In a vacuum pump and well, the combination, with said well, of the following elements: a vacuum-chamber having an induction-pipe and connected by suitable valves with two or more stand-pipes or receivers arranged in pairs and having discharge-valves at their lower and ports open to the atmosphere at their upper ends, a slide-valve operating to alternately open and close said ports to regulate the discharge of the contents of said pipes, as and for the purposes substantially as described.

2. In a vacuum pump and well, the combination, with said well, a vacuum-chamber having an induction-pipe and connected by suitable valves with two or more stand-pipes arranged in pairs and having discharge-valves at their lower and ports open to the atmosphere at their upper ends, and a slide-valve operating as described, of mechanism, as set forth, whereby said slide-valve is reciprocated through the medium of the water tlowinginto the vacuum-chamber, substantially as and for the purposes specified.

3. The combination, with the cylinder B, its induction-pipe B, and the valves 0, of the stand-pipes O 0, connected together attop by a canal, c, and having atmospheric ports 0 and discharge ports and valves 0 at bottom, the valve D, and mechanism, substantially as deseribed,to periodically orintermittingly operate said valve and a suitable air-exhaust apparatus, all constructed to operate substantially as and for the purpose specified.

4. The combination, with the valve D and its operating mechanism, substantially asdescribed, and constructed to operate as set forth, the vacuum-chamber B, the pipe B, and the pipes O U, of the water-motor G, substantially as and for the purpose specified.

5. The combination, with the pipes O O, of the reciprocating slide-valve D and the guard K, arranged to operate as described, and for the purpose set forth.

In testimony whereof we aftix our signatures in presence of two witnesses.
